To all w from it may concern Beit known that I, FREDERICK A. HART,

Newark, in the county of Essex State of New Jersey,- have inventedwcerltaln new and useful Improvements in GopyfHolders. V forType-Writing. Machines, &c., 'ofwhich the following is a specification.

This invention relates to a folding copy holder adapted toforman-attachment for a stand or table, such as a stand; for. a type:-

writer, adding machine, or other machine,

and also usable in other ways.

The invention provldes a copy holder,

which, when not in use may be supported compactly in a pendent position,as for instance it may hang at the sideof the stand'.

orother device to which-it isattaehed, and may be quickly adjustedtmanelevated po+ sition for use. v

The copy holder may comprise a frame portion, to which is pivotallymounted a leaf portion Or support for the copy, and

said leaf when not in use may lie about: in

the plane of the frame. Theframe may be pivoted to a support, as forinstance, a

stand, andmaybe supported thereby in a pendentpositionwhen not in use,andmaybe swung up to a horizontal position for use, and the copysupporting leafmay then be tilted on its frame to-anupwardly andrearwardly inclined position, in which it may be retained by asupporting leg attached to the rear end of the lea-f. 'Saidleg 1 may beprovided with a. notch toengagev the frame when the leaf is lifted, and.a spring may throw said leg upwardly be.-

neath the leaf when the latter is lowered within the frame. Clampstohold the copy against said supportmay. beimountedonthefront endoftheframe to overhang said'sup,

- port, and swingtherewith, thereby. to hold the copy when thesupportis. in either po-.

sition. A lineindic-ator extending laterallyover the copy-holdingsupport may bead; ju'stably mounted; on a.- bar extending along theedge'of thesupport.

Other objects. and" advantages will here? inafter appear.

The stand. or table A comprises. suitably braced front andrear. legs 6andz 7, supports ing a skeleton bed or, top 9, haying; outwardlyprojecting brackets. 9lhy; which the bed: is. connected to the legs.Lugs 9'? project from the bed into thecentralispaoeiine closedthereby,tosupport; a writing or add.

ingfjmachine. 45 (indicated byfidotted: lines As will be seen,themachine occupies practically the entire table top; and to provide asupport for books or papers from which the operator desires to copy, Ihave stand.

downwardly from its operative position. The copy holder at the left (inthe drawings), comprises a frame 2, 2 2", carrying a leaf 17 forsupporting the copy, said frame being rigidly connected by a pair ofsupporting arms 3, 3 to a pintle or rock shaft 4 journaled in bearings5, (see Fig. 10), formed in collars 8, attached to and detachable fromthe forward and rear legs 6, 7 (usually tubular) at one side of thestand below the brackets 9 No special skill is required in attaching thecopy holder to the stand, it being simply necessary to tighten thecollars firmly on the legs.

The collars 8 are secured to the legs below the table top, and thecopy-holder frame 2 is carried at the outer ends of the support-- ingarms 3, 3 which project from the rock shaft between the brackets 9 andsupport the frame when elevated, about-on a plane with the top 9 of thestand.

By hinging the frame 2 as shown, with the pintle 4t at or near the innersides of the legs .6, the copy holder when in disuse,

is caused to lie closely against the table, making a compact structure;while the arms 3 and 3* extend up far enough from the hinge to give thedesired elevation to the frame when in working position; said arms 3 and3 also permitting the copy holder to hang about vertically on. the outersides of the legs, as seen in dotted lines, at Fig. 1.

it will be seen that the inner edge of the copy holder when extended,lies closely adj acent to the side of the table top 9 to preventarticles from falling down between the top and the holder.

To hold the copy-holder frame up, a latch 10 is secured rigidly thereto,the lower free end of said latch 10 engaging a catch 11 mounted on thestand, said catch consisting of a nut threaded on the bolt 13, whichsecures one of the collars 8 on a leg of the The frame is swung up untilthe latch 10 escapes the catch (Fig. 8), whereupon a spring 1-1 shiftsthe frame, with its supporting arms 3, 3 and the pintle or rock shaft4:, in the bearings 5, bodily toward the right (Figs. 4 and 8), so thatthe foot 15 of the latch looks over the catch and supports the frame.The latch may have a stop 16,pressed by the spring 1 1 against the catchor abutment 11.

The latch 10, which may project from one of the arms 3, is preferablyarcshaped, as shown in Fig. 11, and concentric with the hinge pintle, tobear against the catch while the frame is being swung upwardly, and

thereby prevent the lateral shifting of the frame by the spring until ithas been fully raised. A brace 10 to strengthen the latch, may extendfrom the free end of the latter to the rock shaft e.

To drop the frame, it is first pressed edgewise toward the left, (Fig.l), against the tension of spring 14, and caused to rise slightly, so asto release the latch 10 from the catch 11, as shown in Fig. 8. The catch11 and latch foot 15 may be beveled to facilitate this releasingoperation. The frame may now drop freely; the latch 10 acts also as abrake, the spring 1 1 pressing the side of the latch againstthe outerface of the catch, as in Fig. 11, throughout the entire clownward swingof the frame to inoperative position, to retard thedescent of the frane, and prevent it from hanging against the stand.

The copy-holderleaf or plate 17, is hinged to one end 2 of the frame 2,as by straps18, to enable the copy-holder plate to be inclined or tiltedon .its frame (see dotted lines, Fig. 1), the edge of the plate beingrolled over a wire 17 for rigidity. A. bracket 23 on the copy-holderplate engages the opposite end 2 of the frame to limit the swing of theplate. 7

The copy-holder plate 17 is raised to the position shown in dot ed linesin Fig. 4, by a handle 24, the plate pulling with it a supporting leg25, pivotally connected to the bracket 28 by a bolt 30 and nut 29, saidleg being drawn across the end 2 of the frame until a recess 27 at thefree end or foot 26 of the leg catches over said end. To lower thecopy-holder plate or leaf 17, the leg is disengaged from the frame.

The leg may be pressed against the frame end 2 by a spring 28 as theleaf 17 is raised, to insure that the recess 27 shall catch over saidframe end. Said leg is connected to the bracket so as to lie against theouter face of the frame end 2, and when the leaf 17is lowered, thespring operates to swing the leg up under the frame 2, 2 where it is outof the way, (full lines, in Fig. l), and by clasping tie frame end 2between itself and the bracket 23, operates to lock the holder leafagainst accidental tilting, when the frame 2 is dropped. The tension ofthe spring 28 is regulated by the nut 29, to which one end of the springis connected, the opposite end being connected to the leg (as shown inFigs. 6 and 7 said nut being held where adjusted by a pin 31 seated inthe bracket and fitting any one of a series of notches 32 in the nut.

A finger 83 extends across the copy-holder to enable the operator toreadily follow the copy. Said finger is connected by a sleeve 3a to rockupon and slide along a helix or screw constituting a cylindrical rack 35at one side of the copy-holder, and has a handle 87 whose hub 88 isslidable on the rack and accommodated in a recess in the sleeve 34, saidhandle being foldable, as shown in dotted lines in Fig. 3, forcompactness. The handle is arrested in operative position, (Fig. 5), byflattening the hub as at 4a to engage the wall of the slot in the sleeve3%. A spring-pressed detent 39 cooperating with the rack teeth &0,prevents accidental movement of the line indicator.

A paper clamp 19 swings on the shaft 2 of the frame, to tilt with thecopy-holder and to catch over the bottom edge of the paper thereon, saidclamp having a handle 20. A boss 21 on the clamp bears upon the walls ofa groove 22 in the shaft 2* to hold the clamp frictionally whereadjusted.

The opposite side of the stand may be equipped with a drop leaf, ifdesired, that shown comprising a frame 42, 42 42 hinged to the stand,similarly to the frame 2, and carrying a plate 4:3 fixed thereto by theclips or straps 44.

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without others.
